Did not weld it. This an alloy (aluminum) frame and fork. That would have required a TIG welder, which I did not have, and there is always the
danger that the thin metal might have warped. Instead, I drilled two holes and through bolted (SS cap screws) a piece of aluminum bar stock (threaded) to the
fork and then mounted the brake to that aluminum piece. That gave me the right spacing for the brake to fit the rotor. The Shimano disc brake comes with angled
washers that allow a good range of adjustment so the brake caliper and the rotor can be aligned easily.
